bug#20686: "No access to tty" in Emacs shell

["Warren, John W CIV (US)" <john.w.warren.civ@mail.mil>]

Error message in *shell* buffer on entering shell mode:
"Warning: no access to tty; thus no job control in this shell..."

Note: The affected system does not have an internet connection,
but I can sneaker-net files across.
